Woodward ProTech-GII - Bulkhead Mount, HV/HV, Voted Relays 8237-2597

The TMR5200 Module is designed for 3-2-0 operation. A TMR system cannot operate with a single CPU.

This module was designed and rated for –40 to +85 °C operation in the industrial marketplace.

RTN Port

In a TMR5200 based system, each Kernel CPU provides Real Time Network (RTN) capability for

expanding to other racks using Ethernet port 4 (RJ45). This RTN port communicates between the main

chassis CPU's and any Remote RTN modules located in an expansion chassis. The GAP software

application defines the expansion racks, their I/O modules, and the use of the RTN port (GAP block is

RTN).

Up to two Remote RTN modules may be installed into each MicroNet Plus 8/14 expansion chassis (only

one RTN for 6/12 slot expansion chassis). When initialized by the main chassis CPU, the Remote RTN

modules will acquire either a SYSCON or STANDBY status. The Remote RTN module that becomes

SYSCON will control the expansion chassis where it is located. It will synchronize with the STANDBY

Remote RTN module and perform any redundancy functions as necessary. Input and output data from all

I/O modules will be managed appropriately and made available to the GAP Application running in the

main-chassis CPUs.

The MicroNet Remote Real Time Network (RTN) module is designed to be located in an expansion rack.

The module’s primary function is to gather data from local I/O modules and communicate this data to the

main rack CPUs while providing redundant failover control of the rack in which it is located.

The Remote RTN module contains a MPC5200 processor, 128 Mbyte DDR RAM, 64 MB of flash

memory, a Real Time clock, and various communication peripherals. These peripherals include (3) Real

Time Network ports and (1) service port. This module includes an FPGA to provide VMEbus master/slave

capability, health monitoring, and failover functions necessary for redundant systems.
